Description: |
| Abstract:
This invention relates to a device for bending angle irons, channels, I-beams, strips, bars, and similar objects, and more specifically for bending such objects of different sizes with one standard form or die. In general, it is an object of the invention to provide a device of the character described which will efficiently perform the purposes for which it is intended, which is simple and economical of construction, which can be expeditiously, conveniently and safely manipulated, and which can be readily manufactured and assembled. Another object of the invention is to provide a device with which angle irons, etc. may be bent more than 180 degrees and then be easily removed from the device; to provide such a device which may be readily converted for use in bending objects of different thicknesses and sizes; and to provide such a device which uses the forces of compression rather than the forces of rolling.
Claim:
In combination, a device for bending structural sections and the like comprising a form having a surface against which one face of an angle iron may be pressed, a second form which is coaxial with the first-mentioned form and which has a surface against which the edge of another face of the angle iron may be pressed, end elements having areas of cross-section perpendicular to the axis of said device which are larger than similar areas of the respectively adjacent forms, said elements being axially removable away from said forms and means for temporarily holding one of said end elements and the first-mentioned form in a press fit respectively against the two surfaces of such angle iron which are adjacent such a before-mentioned edge of such an iron. |
